Application filed January 23, 1917. Serial No. 144,030.

To all whom it may concern:

Be it known that DANIEL MoCALLIs'rnn, a citizen of the United States residing at Curtisville, in the county of Allegheny. and State of Pennsylvania, have invented new and useful Improvements in Rail-Joints, of which the following is a specification.

This invention relates to a rail joint and has for its primary object to provide a rail joint that may be easily removed from the rail but still capable when in use to support the rail ends against lateral play.

An object of the invention is the manner of forming one of the plates with an abutment and associating the same with the base portion of the rails for preventing creeping of the latter but still capable of accommodating expansion and contraction of the rail.

Besides the above my invention is distinguished in the novelmanner of associating the plates and further associating the same with a bond so that the resistance of the bond will be materially reduced due to the fact that the surface in contact between the bond and rail is increased.

With these and other objects in view the invention will be better understood from the following detail description taken in connection with the accompanying drawings wherein Figure 1 is a sectional view through a rail showing the plates in end elevation.

Fig. 2 is a perspective view of one plate.

Fig. 3 is a top plan view of the other plate.

Fig. 4: is a top plan view of the rail bond.

Fig. 5 is a sectional view through one of the plates showing the abutment associated with the rail.

Fig. 6 is a detail view of one end of a rail.

Fig. 7 is a longitudinal sectional view of the joint. 7

Fig. 8 is a top plan view of a modified form of plate.

Again referring to the drawings the numerals 1 and 2 designate a pair of plates each having an upright portion 8 and a base portion 4:. Each plate is further provided with an inclined shoulder 5 cooperating with an inclined edge 6 of the associated plate while the plate 1 is provided throughout its length with a groove 7 receiving the correspondingly shaped rib 8 on the other plate.

From this arrangement it will be seen that the plates may be disassembled by moving the same in opposite directions longitudinally of the rail ends 9 and 10.

Between the upright portion 3 and the web of the rail is a rectangular bond 11 having tapering projections 12 entering correspondingly shaped recesses 13 in the web of the rail ends. From this arrangement it will be seen that the bond is sheltered and the entire length thereof is brought into contact with the web for insuring a good electrical connection between the rail ends and the bond and besides prevents anyone from removing the bond except by disassembling the joints.

In Fig. 8 the plate is identical in construction with the plate 2 with the exception that the rib l l extends at an angle and engages a correspondingly arranged groove in the other plate (not shown) so that the plates will have a wedge action with each other for moving the same toward the web of the rail ends for insuring a tight connection and for the additional purpose of forcing the bond into tight contact with the rail ends.

The plate 1 has formed upon the base portion an abutment 15 tapering in opposite directions from a central point as indicated at 16. As clearly shown in Figs. 6 and 7 of the drawings each rail end is provided with a recess 17 of a shape to snugly receive the abutment l5. lhis abutment may be formed integral with the plate as indicated in Fig. 7 or detachably secured thereto by bolts or other securing elements.

From the foregoing description taken in connection with the accompanying drawings it will be seen that in a very simple manner I provide a rail joint that will effectively hold the rail ends against spreading or creeping and in such a manner that the member may be manufactured in an inexpensive manner.

Having described my invention What I triangularly shaped in cross section and taclaim is: pering in opposite direction from a central 10 In combination with a pair of rail ends point, said recesses combining to form a a each having a recess formed at the end of space corresponding in shape and receiving 5 the base, a jointcomprising a pair of plates said abutment.
